About this item

VERSATILE - This mortar joint repair sealant can be used to seal and waterproof joints, cracks and gaps. Bonds well to construction materials like bricks, blocks, masonry, stucco and metal frames
DURABLE - Suitable for indoor and outdoor use, this moisture-curing polyurethane-based sealant forms long-lasting seals that are age, weather, water and stress-resistant. Service range: -40°C to 77°C
FLEXIBLE - This non-sag elastomeric sealant is highly elastic, making it a great choice for expansion joints. It forms strong yet flexible seals with exceptional resistance to cutting and tearing
TEXTURED - Sikaflex Mortar Fix has a textured finish that blends well into rough surfaces like stucco. Great for DIY home repairs, it hides imperfections that would be obvious with a smooth sealant
EASY TO USE - Suitable for both horizontal and vertical use, this one-component sealant can be applied to most materials without priming. Cures with exposure to moisture in air. Paintable after curing

Its super easy to use. Just cut the top and squeeze it where you need it. I think for bigger holes its a little costly as you don't get that much in a tube. I do recommend it

Product was a lot lighter in color than my existing mortar. Had a hard time dispensing out if the tube, kinda messy. But, it does appear to be holding the loose bricks though…

I bought the one that is colored limestone, but it looks silver next to my mortar. I'll take another picture in a week or so once it's had time to cure to see if it changes colors.

Either way, it is exactly the color that is shown from the manufacturer in the pictures when it comes out of the tube.

Mortar Fix

This is just the right texture & consistency for caulking the limestone of my house. There were hairline cracks in the limestone where I could see daylight from the garage to outside. Filling the cracks horizontally is easy with this product as it doesn’t easily leak out. I used this product name for self leveling sidewalks & the driveway also. Very happy with this brand. Be sure to use something such as paper towel or rag to catch the flow till you get it in the upright position. Otherwise quite messy.
